Abstract

Cold spray (CS) technology has proven a great potential in the production of composite coatings, enabling the production of materials with superior qualities such as enhanced tribological behavior. This study aims to investigate the tribological properties of CS Al-based composite coatings reinforced by quasicrystalline (QC) particles. Two different Al alloys were used as the matrix, AA 6061 and AA 2024, and mixed with Al-based QC particles (Al-Cr-Fe-Cu) at different Al/QC ratios. A room-temperature ball-on-disc test was then used to evaluate the wear resistance of the composite CS coatings in air and compared to those of the non-reinforced Al alloy CS coatings as well as a cast counterpart (AA 6061-T6). We have demonstrated that CS could be employed to produce thick and dense Al-QC composites that can retain up to about 50 wt.% QC reinforcement in the structure. The incorporation of the QC particles increased the wear resistance by a factor of 7.

冷喷铝/准晶复合涂层耐磨性对比研究

冷喷（CS）技术已被证明在生产复合涂层方面具有巨大潜力，可生产出具有卓越品质（如增强摩擦学行为）的材料。本研究旨在探讨由准晶体（QC）颗粒增强的 CS 铝基复合涂层的摩擦学特性。研究使用了两种不同的铝合金（AA 6061 和 AA 2024）作为基体，并以不同的铝/QC 比混合了铝基 QC 颗粒（铝-铬-铁-铜）。然后使用室温球盘试验来评估复合 CS 涂层在空气中的耐磨性，并与非增强型铝合金 CS 涂层和铸件（AA 6061-T6）的耐磨性进行比较。我们已经证明，CS 可以用来生产厚而致密的 Al-QC 复合材料，在结构上可以保留高达约 50 wt.% 的 QC 增强成分。QC 颗粒的加入使耐磨性提高了 7 倍。
